The mask according to the present invention having the above-described configuration has the following excellent functions as compared with the conventional mask. On the back surface of the mask body, the mask body is sewed inwardly from the center of the upper and lower edges in a V-cut shape, thereby improving the adhesion with the raised nose portion at the center of the upper edge of the mask body. At the same time, the adhesion with the cheek portion of the face is improved at the center of the lower edge of the mask body. Therefore, it is possible to remarkably enhance the function of preventing dust and viruses from sucking in the upper and lower portions of the mask.

Embodiments of the present invention will be specifically described below based on examples of the present invention shown in the accompanying drawings.

First, an embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a perspective view of the unfolded mask A in this embodiment as viewed from the front surface, FIG. 2 is a perspective view of the mask A as viewed from the back surface, and FIG. 3 is an explanatory view of the state where the mask A is mounted. .

As shown in FIG. 1 as a perspective view seen from the surface of the mask A, the mask A includes a mask body 1 having a size and shape sufficient to cover the mouth and nostrils, and left and right side edges 3 of the mask body 1. Each of 3 'is provided with rubber ring-like ear straps 2, 2'. And in the center part of the up-and-down edge 4 and 6 of the mask main body 1, the V cut-shaped sewing shrinking parts 5 and 5 'are provided up and down. When the upper and lower portions of the center portion of the mask body 1 are V-cut and sewed together, the swollen curve at the center portion becomes longer than the left and right side edges 3, 3 '.

On the other hand, as shown in FIG. 2 as a perspective view seen from the back surface of the mask A, the upper end portion of the mask body 1 is inclined at the center of the edge 4 above the mask body 1 via the seam shrinking portion 5. As left and right. The inclined surfaces 7 and 7 extend left and right while bending in the direction of the back surface of the mask A with a line connecting the vertex P and the vertex Q as a ridge, and form a roof-like cover from above the mask body 1.

On the other hand, at the center of the edge 6 below the mask main body 1, the lower end portions of the mask main body 1 are formed on the left and right sides as the inclined surfaces 8, 8 via the seam shrinking portion 5 ′. The inclined surfaces 8 and 8 extend from side to side while bending in the direction of the back surface of the mask A with a line connecting the vertexes P ′ and Q ′ as a ridge, and have a hook shape below the mask body 1. Here, the bowl shape means a tray formed by the inclined surfaces 8 and 8 below the mask body 1, that is, a tray.

The back side of the mask A extends from the upper side of the mask body 1 while the inclined surfaces 7 and 7 are bent toward the back surface of the mask A to form a roof-like cover of the mask body 1. On the other hand, the inclined surfaces 8, 8 extend from the lower side of the mask main body 1 while being bent toward the back surface of the mask A, and a bowl-shaped receiver is formed below the mask main body 1. In this way, on the back side of the mask A, a roof-like cover formed by the inclined surfaces 7 and 7 from above, and a bowl-shaped receiver and the mask body 1 surface formed by the inclined surfaces 8 and 8 from below.
